生物活性

YM022 is a highly potent, selective and orally active gastrin/cholecystokinin (CCK)-B receptor (CCK-BR) antagonist. YM022 shows the Ki values of 68 pM and 63 nM for CCK-B and CCK-A receptor, respectively. YM022 can inhibit gastrin-induced gastric acid secretion and histidine decarboxylase activation in vivo.

体外研究

YM022 inhibits binding to canine pancreas CCK-A receptor in a dose-dependent manner, with an IC50 value for [H]devazepide binding of 136 nM.
YM022 inhibits the binding of [I]CCK-8 to canine cloned gastrin/CCK-B receptor in a dose-dependent manner, with an IC50 value for [I]CCK-8 binding of 0.73 nM.
Selectivity [ratio of (IC50 for gastrin/CCK-B receptor)/(IC50for CCK-A receptor)] of YM022 is 186.

体内研究

YM022 (intravenous injection; 0.01-1 μM/kg) dose-dependently inhibits pentagastrin- and peptone meal-induced acid secretion with ED50 values of 0.0261 and 0.0654 μmol/kg, respectively, without affecting histamine- or methacholine-induced acid secretion.
YM022 (subcutaneous injection; 300 μmol/kg; single dose) lowers the oxyntic mucosal HDC activity and raises the serum gastrin concentration in a dose-dependent manner (measured 24 h after dosage). Maximum enzyme inhibition is achieved at a dose of 300 μmol/kg  for YM022 and the inhibition of HDC lasts for 4 weeks. At sacrifice, drug residues can be seen at the injection site for as long as 4 (YM022) weeks after injection in rat.
YM022 is suspended in 2% Methocel for oral ingestion and in PEG300 for subcutaneous injection.

Animal Model: Rat
Dosage: 300 μmol/kg
Administration: Subcutaneous injection; 300 μmol/kg; single dose
Result: Suppressed the ECL cell activity for at least 4 as manifested in greatly reduced HDC activity, greatly elevated serum gastrin level.

    请依序添加每种溶剂: 10% DMSO    90% corn oil

    Solubility: ≥ 2.5 mg/mL (4.84 mM); Clear solution

    此方案可获得 ≥ 2.5 mg/mL (4.84 mM,饱和度未知) 的澄清溶液,此方案不适用于实验周期在半个月以上的实验。

    以 1 mL 工作液为例,取 100 μL 25.0 mg/mL 的澄清 DMSO 储备液加到 900 μL玉米油中,混合均匀。
